MAPS™ LTE SGs Emulator

Overview

GL’s Message Automation & Protocol Simulation (MAPS™) SGs Emulator is designed to realize the CS fallback function for Voice and SMS delivery via the Circuit Switched (CS) core network using SGs interface between the Mobility Management Entity (MME) in the Evolved Packet System (EPS) and the Visitor Location Register (VLR), as defined in 3GPP TS 29.118 specifications (SGsAP) SGs interface.
The application is available as

MAPS™ LTE SGs (Item # PKS146) for SGs interface

The MAPS™ SGs Emulator implements the following SGsAP procedures when associations between an MME and a VLR are established:

Paging for Non-EPS Services
Location Update for Non-EPS Services
Non-EPS Alert
Explicit IMSI Detach from EPS Services
Explicit IMSI Detach from Non-EPS Services
Implicit IMSI Detach from Non-EPS services
VLR Failure
MME Failure
MM Information
Tunnelling of NAS Messages
Mobile Terminating and Mobile Originating SMS Services

Coming soon is the MAPS™ SGs emulator integration with GL’s multi-protocol and multi-interface lab test solution, covering entire 2G, 3G, and 4G networks simulating CSFB over SGs interface between LTE MME and UTRAN MSC.

By mimicking real-world customer behavior in lab environments, our solutions allow mobile operators and equipment manufacturers to verify their wireless networks before deployment. In other words, one can setup a virtual real-time network simulating all the network elements using “MAPS 2G 3G 4G Wireless Lab Suite”. The test suit supports simulation of 2G, 3G, and 4G entities and connecting interfaces.
